IMPROVEMENT IN CULTIVATORS.

Specification forming part of Letters Patent No. 96,126, dated October 26, 1869; antedated October 16, 1869.

To all whom it may concern:

Be it known that I, JAMES H. LOOKIE, of Humphrey, in the county of Gattaraugus and State of New York, have invented a new and useful Improvement in Cultivators; and I clear, and exact description thereof,whichwill enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a top or plan view'of my improved cultivator. Fig. 2 is a side view of the same, partly in section, through the line 90 m, Fig. 1. Fig. 3 is a detail view of the clamping device for securing the adjustable wings in place. Fig. 4 is a detail view of the clampingbolt.

Similar letters of reference indicate corresponding parts.

My invention has for its object to furnish an improved cultivator which shall be so constructed and arranged that it may be readily adjusted to cultivate rows of plants at different distances apart, and which shall at the same time be strong, durable, and not liable to get out of order, or be broken by striking a stone or other obstruction; and it consists in the construction and combination of the various parts of the cultivator, as hereinafter more fully described.

A is the central beam, and B are the side beams or wings, of the cultivator-frame. The forward end of the central beam is curved up ward, as shown in Fig. 2. The beams A and B are each made of two parallel iron bars secured to each other so as to leave an opening or slot between them, as shown in Fig. 1.

O is a three-armed piece or plate, to the central arm of which the forward end of the central beam, A,is attached, and to the ends of the side arms of which the forward ends of the side beams or wings, B, are hinged, as shown in Figs. 1 and 2, so that the rear ends of said side beams may be moved out or in, to make the cultivator wider or narrower, as may be desired.

To the rear parts of the beams Bare attached the outer ends of the arms D, the inner ends of which pass over the upper side of the central beam, A, to which they are adj ustably clamped by the cross-head bolt E, cap F, and nut G. The bolt E passes up through the slot in the central beam, A, upon the lower edges of which the arms of its cross-head take hold. The arms of the cap F take hold of the arms D upon each side of the bolt E, as shown in Figs. 1, 2, and 3, so that when the bolt E and cap F are drawn closely upon the beam A and arms D by the nut G, the said arms Dmay be clamped so closely to the beam A as to hold the side beams, B, securely in place.

H is the draft-bar, which is made in about the shape shown in Fig. 2, the middle part of which is secured to the curved forward end of the central beam, A, by a bolt passing through a hole in the end of the beam A and through the bar H, or above the said bar H, according as it is desired to have the line-of draft higher or lower. The rear end of the draftbar H is adjustably secured in the slot of the beam A by a bolt passing through the beam A and through one or the other of the holes in the rear end of the said bar H.

I are the cultivator teeth or plows, which are formed solid with their standards J. The bodies of .the standards J are bent forward, as shown in Fig. 2, and their extreme forward ends are turned upward, as shown. standards J are pivoted at their angles in the slots of the beams A and B by bolts passing through the angles of the said standards and through the said beams. The forward ends of the standards J are secured to the beams A and B by wooden pins passing through the said beams and through one or the other of the holes in the said forward ends of th standards, to give the desired pitch to the cultivator-teeth. These wooden pins should be of such a strength as to sustain the ordinary draft-strain of the teeth, but which, should the said teeth strike an obstruction, will break and allow the teeth to swing back upon the bolts that pass through the angles of their standards, so as to pass the obstruction without being broken.

K are the handles, the rear ends of which are connected and held in their proper rela tive positions by a cross-bar or round. The rear parts of the handles K are supported by brace-bars L, the lower ends of which are secured the rear end of the central bar, A. The

The 4 The comwinittion, with the central beam, A, of the outer beams, B B, when the same are constructed as described, and connected by the three -arrned piece 0, substantially as described, for the purpose specified.

The above specification of my invention signed by me this 22d day of January, 1869.
